Abstract

Abstract A semiconductor integrated circuit device has a semiconductor chip, on which are formed a plurality of input/output circuits and input/output pads individually connected electrically thereto. The input/output pads are connected electrically to a plurality of inner leads formed on the frame on which the semiconductor chip is mounted. The input/output circuits are arranged in two rows along each edge of the semiconductor chip, with the first row of input/output circuits arranged closer to the edge than the second row of input/output circuits. The input/output pads connected to the first-row input/output circuits are arranged in two rows in such a way that the first and second rows of input/output pads sandwich the first row of input/output circuits. The input/output pads connected to the second-row input/output circuits are arranged to form a third row of input/output pads along the second row of input/output circuits.
